Using the Adventure Pack is easy. First, adjust the harness straps to fit your dog properly. Make sure it's not too tight or too loose so your dog can move around comfortably. Attach the leash to the aluminum dees. The detachable packs can be filled with your dog's supplies. When you're done with the adventure, you can remove the packs easily. As for maintenance, keep it clean by wiping it down with a damp cloth. If it gets wet, let it dry thoroughly. Check the zippers and straps regularly for any signs of wear and tear. Also, don't over - load the packs as it might affect your dog's comfort and movement.
